Answer: 15c
Step-by-step explanation:
When you come across any question that mentions [the product of a and b] means a × b
- the product of 6 and 7 is 42, 6 × 7=42
- the product of x and y is xy, x × y=xy
<u>Solve:</u>
The product of 15 and c
<h2>15 × c=15c</h2>
Answer:
Step-by-step explanation:
<u><em>The complete question is</em></u>
Three times the sum of a number and two is less than seven times the number. Find the number
Let
x -----> the number
we know that
The linear equation that represent this problem is
Solve for x
Apply distributive property left side
Subtract 3x both sides
Divide by 4 both sides
Simplify
Rewrite
Answer:
Equation: y = 5x - 2
Step-by-step explanation:
<em>Slope = Change in y / Change in x</em>
Change in y = +5
Change in x = +1
<u>Slope = 5/1 or 5</u>
<em>Y-intercept = y-value where x = 0</em>
x = 0, y = 3-5
y = -2
<u>y-intercept = -2</u>
Finally;
<u>Equation: y = 5x - 2</u>

Answer:
1.66
Step-by-step explanation:
The mean of a set of data is 4.68 and its standard deviation is 2.83. Find the z score for a value of 9.38
Given that :
Mean (m) = 4.68
Standard deviation (s) = 2.83
Value of x = 9.38
Zscore = (x - mean) / standard deviation
Zscore = (9.38 - 4.68) / 2.83
Zscore = 4.7 / 2.83
Zscore = 1.6607773
Hence, Zscore for a value of 9.38 is 1.66
